Nightfallen rep stuck at 5975/6000, still have quests

Anyone else run into this? I got to 5975/6000 last night, had 6 more quests completed and not a single one of them gave me nightfallen rep. I was in Felsoul and one of the quest lines ended with Thalyssra, and I can't imagine at least that step wouldn't have given me some rep. Did I miss a step that is locking me out of rep? Its particularly frustrating because I feel like I wasted those turn ins.
